In this paper we present an architecture for the integration, into a common framework, of multimedia broad-band services for long-distance cooperative work and ubiquitous access to data and resources. The integration architecture is based on a pool of servers whose interaction offers several
functionalities: they define the underlying information system and the access rights, manage the web-based access to services and guide the interaction of services during the cooperative work sessions. In particular, a web server controls the interaction between users and the system, a directory
(LDAP) [1] [2] [3] and a database (SQL) servers maintain the information system and a messaging server
(Jabber) is used as a communication tool for the applications.
